Yahoo mail: how do I set up an e-mail to a group?

I’d like to set up an e-mail to a group of my contacts, without the recipients of the e-mail seeing who else got it, or the other people’s e-mail addresses. How do I do that?

Click on the “CC” in the upper right hand corner of the compose window. Then click on the “BCC”. Put all the clients’ email address in the BCC line, put your own email on the “To” line and no one will see anyone else on the mail.

Thanks! Is there a way I can set up a set of contacts, so I don’t have to fill in all the bcc addresses individually?

I can’t speak for Yahoo specifically (sorry), but all email clients I’ve used allow you to put an address book group in the BCC field.
